Just seconds after leaping from the plane during a skydiving event, James Lee, 25, was accidentally hit on the back of the head by another skydiver. The blow knocked Lee unconscious and sent him hurtling 12,500 feet down towards the ground.

Two skydivers noticed that something was wrong and chased Lee down, reported The Telegraph. Realizing that he was unconscious, the two men managed to stabilize his position and deployed his parachute. Lee landed safely on the ground but didn't realize what had happened until he saw the amazing footage of the dramatic mid-air rescue that was captured by his helmet cam. Watch:

Looking at the footage, Lee said:

"At first the other skydivers give basic hand signals that we teach our students with to correct their body position and find I am still not responding.

"They manage to get hold of me to try and stop my body tumbling again as we get closer to the altitude where, as a group we separate to deploy our parachutes.

"They signal to the other jumpers to get away as they were unaware of what was happening. They then deploy my main parachute. Once I was clear they deployed their own."

Lee, a veteran skydiver, said that he has no plans to give up skydiving despite his near-death experience.
